Hi Thomas, >../configure --prefix=/opt/gcc-4.2.2 --enable-version-specific-runtime-libs --enable-static --enable-shared --enable-languages=c,c++,java,objc,obj-c++ --enable-threads=posix --enable-nls --enable-__cxa_atexit --enable-libstdcxx-debug --enable-checking=release x86_64-linux-gnu It appears that you are attempting to build GCC from within a subdirectory of the GCC source code (instead of, say, a peer directory to the GCC source code). Since that situation is not supported as per <http://gcc.gnu.org/install/configure.html>, do you get the same problem if you build to a peer directory to the source code? Note: the source code tree may be "tainted" and could need to be "rm -rf" and "tar -x" afresh. I do not know if this is related to the problem encountered or not. Just one of the variables to consider taking out of the equation. Sincerely, --Eljay
